I was just trying to remember the team that did that a couple years back. I could see that happening, too.
As some have said in here, I think I'd prefer to keep this game vanilla and see what happens. It just seems like when we see the Chiefs in the playoffs, our gameplan is to replicate what we did in the regular season, and Spag/Reid have it squashed.
Try something different, and make it drastic, and it could take their coaching out of the playoff game enough to squeeze by them.
